Ketamine can be a wonder drug for ER patients and their physicians

A systematic review of 10 studies confirms ketamine's safety in critically ill patients, providing analgesia, sedation, and amnesia without significant increases in intracranial pressure or neurological outcomes. The findings support the use of ketamine as a routine treatment for life-threatening infections and unconscious patients.

Discovery is key to metal wear in sliding parts

A team of researchers has discovered a previously unknown mechanism for wear in metals, which could lead to improved durability of metal parts. The findings show that tiny bumps and surface defects can form through a swirling, fluid-like behavior in solid metals, leading to cracks and wear particles.

Hormones after breast cancer: Not fuel for the fire after all?

Researchers found that bioidentical hormone treatments reduced tumor recurrence and improved cardiovascular and bone health, while also increasing physical activity and cognition. The study's results are promising but require further validation, providing a new direction in the search for alternative hormone therapies.
